Edit: 2019-12-30. V3 - increased the pad 'bump' (center circle for support) from 0.3mm height to 0.6mm and increased diameter to 3.5mm.

Printed and tested.

Edit: 2019-09-23: If the vibrate stopped working (mine stopped a few months ago) - see this link

Edit: 2019-09-22: V_2 as the center of the cap failed after a year.

The pad part is also now 0.3mm (previously 0.5mm)
